【摘要】 观察复合树脂充填后牙牙合面磨耗凹坑及前牙切缘磨耗凹槽的临床疗效。首先确定磨耗的凹坑及凹槽是否有足够的充填空间,必要时调磨对牙合过锐过陡的牙尖及牙嵴,彻底清洁窝洞,然后在不备洞的情况下,采用可乐丽菲露黏接剂及相应复合树脂充填窝洞。70颗患牙随访1a,成功52颗,有效16颗,失败2颗,有效率为97.14%。本法避免了因备洞而危及牙髓的问题,且易被患者接受,操作简便,易于推广应用。更多还原

【Abstract】 The purpose of this study was to evaluate the clinical effect of using composite resin to fill dental attrition on occlusal surface. Whether the dental attrition had enough space to the material was determined first. Sometimes grinding the sharp and steep cusps or ridges of the opposite teeth was needed. Then the dental attrition was cleaned thoroughly, and finally filled with CLEARFIL bond and composite resin without preparing cavity. The follow-up period was 1 year . Out of 70 teeth from 25 patients, 52 were successful, 16 were curative, and 2 were failed. The curative rate was 97.14%. The method avoids endangering the dental pulp. It was easily accepted by the patients and operated by dentists, and can be widely applied in clinical cases.更多还原
